Description
本発明はデラミボトル及び該ボトルの外気導入孔形成方法に関する。 The present invention relates to a delami bottle and a method for forming an outside air introduction hole of the bottle.
デラミボトルとして、保形性を有する外層の内面に可撓性の内層を剥離可能に積層し、外層には外気導入孔を設けて構成され、装着したポンプ等による収容液の減少に伴って内部が負圧化し、内層が外層より剥離収縮するとともに、外気導入孔より内外層間に外気が導入されるものが知られている。 As a delamination bottle, a flexible inner layer is peelably laminated on the inner surface of a shape-retaining outer layer, and an outer air introduction hole is provided in the outer layer. It is known that negative pressure is applied, the inner layer is peeled and contracted from the outer layer, and outside air is introduced into the inner and outer layers from the outside air introduction hole.
この種のデラミボトルに於ける外気導入孔は上記した如く外層部分に設けられており、例えば口頸部を構成する外層に形成されているが、外層に対する内層の密着程度が強く、口頸部に於ける外層部分と内層部分との剥離が円滑に行なわれず、内容物の円滑な吐出が阻害されたり、外層に外観体裁の悪い不正陥没変形が発生するという虞があった。 As described above, the outside air introduction hole in this type of delami bottle is provided in the outer layer portion, for example, formed in the outer layer constituting the mouth and neck portion, but the inner layer is closely adhered to the outer layer, In this case, the outer layer portion and the inner layer portion are not smoothly separated from each other, and the smooth discharge of the contents may be hindered, or an unauthorized depression deformation with a bad appearance appearance may occur in the outer layer.
この様な点を考慮して、デラミボトルにおける外層部分に対して、内層部分を予め剥離させておくとともに、この剥離状態を保持することを技術課題とし、もってデラミボトルに於ける外層と内層との間への外気の導入通路を確保し、これにより内容液注出に伴う、容器の不正変形の発生を確実に防止するデラミ容器が提案されている。（例えば、特許文献１参照） Considering these points, the technical problem is to keep the inner layer part peeled from the outer layer part in the Delami bottle in advance, and to maintain this peeled state, and therefore between the outer layer and the inner layer in the Delami bottle. There has been proposed a delamination container that secures a passage for introducing outside air into the container and thereby reliably prevents the container from being illegally deformed when the content liquid is poured out. (For example, see Patent Document 1)
特許文献１に記載のデラミボトルは、口頸部の外層部分に外気導入孔を貫通開口し、外層部分の外気導入孔開口縁の内表面近傍部分を反り返り状に塑性変形させて外層部分の内表面から突出する突出部を形成し、この突出部で外気導入孔付近の内層部分を外層部分から押し離し状態とし、内層部分と外層部分との間に剥離空間を形成している。 The Delami bottle described in Patent Document 1 has an outer air introduction hole penetrating through the outer layer portion of the mouth and neck, and a portion near the inner surface of the outer air introduction hole opening edge of the outer layer portion is plastically deformed in a warped shape to cause an inner surface of the outer layer portion A projecting portion projecting from the outer layer is formed, and the inner layer portion in the vicinity of the outside air introduction hole is pushed away from the outer layer portion by this projecting portion, and a separation space is formed between the inner layer portion and the outer layer portion.
本願発明は上記従来例と同様に容器の不正変形の発生を確実に防止でき、ポンプを装着した際の円滑な内容物の吐出が可能であるデラミボトルを提案するものであり、また、外気導入孔の穿孔に当たって内層を損傷することなく行なえ、上記した特徴を備えたデラミボトルの形成が可能な、デラミボトルの外気導入孔形成方法を提案する。 The present invention proposes a delamination bottle that can surely prevent the occurrence of unauthorized deformation of the container as in the above-mentioned conventional example, and that can smoothly discharge the contents when the pump is mounted, and also has an outside air introduction hole. A method for forming an outside air introduction hole of a delami bottle is proposed, which can be performed without damaging the inner layer in the perforation, and can form a delami bottle having the above-described characteristics.

In a delamination bottle in which a concave portion 12 is provided in a portion of the body portion 10 located in the peeling region of the inner layer, and an outside air introduction hole h is formed in an outer layer o portion inside the concave portion,
As the concave portion 12, a pair of concave portions 12 is provided at a part of the body portion 10 with a space therebetween, and an outside air introduction hole h is formed in the opposing wall 13 adjacent to the outer layer o forming each concave portion 12.
第１の手段は、上記基本的な構成を有し、かつ、上記凹部１２として、胴部１０の一部に間隔をあけて一対の凹部１２が設けられ、各凹部１２を形成する外層ｏの隣接する対向壁１３に外気導入孔ｈが形成された。The first means has the above-described basic configuration, and a pair of recesses 12 are provided at a part of the body 10 as the recesses 12 with a space therebetween, and the outer layer o that forms each recess 12 is provided. An outside air introduction hole h was formed in the adjacent opposing wall 13.
第２の手段として、以下の通り構成した。即ち、本発明のデラミボトルは、前記第１の手段に於いて、一対の対向壁１３にそれぞれ外気導入孔ｈを穿設し、各外気導入孔ｈに挿通して吊り下げ紐２０を装着した。 The second means is configured as follows.

That is, in the delamination bottle of the present invention, in the first means, the label 40 is mounted on the outer periphery of the body portion 10 so as to cover each recess 12.
第５の手段として、以下の通り構成した。即ち、本発明のデラミボトルの外気導入孔形成方法は、胴部１０上に口頸部１１を起立するとともに胴部１０の一部に凹部１２を設けた形態をなし、保形性を有する外層ｏの内面に剥離可能に内層ｉを積層形成した外気導入孔未形成ボトルＡ１を、ブロー成形により形成し、次いで、外気導入孔未形成ボトルＡ１の内部を減圧して内層ｉを外層ｏより剥離収縮させ、しかる後内層ｉの剥離収縮状態で上記凹部１２内の外層ｏ部分に外気導入孔ｈを穿設し、次いで、剥離収縮状態の内層ｉ内をブロー加圧して内層ｉを拡張し、内層ｉを外層ｏに積層したことを特徴とする。 The fifth means is configured as follows. That is, the outside air introduction hole forming method for a Delami bottle according to the present invention has a form in which the mouth neck portion 11 is erected on the trunk portion 10 and the concave portion 12 is provided in a part of the trunk portion 10, and the outer layer o having shape retention is provided . An outside air introduction hole non-formed bottle A1 in which the inner layer i is laminated and formed on the inner surface of the outer layer is formed by blow molding, and then the inside of the outside air introduction hole non-formed bottle A1 is decompressed to peel the inner layer i from the outer layer o. Thereafter, an outside air introduction hole h is formed in the outer layer o portion of the recess 12 in the peeled and contracted state of the inner layer i, and then the inner layer i in the peeled and contracted state is blown and pressurized to expand the inner layer i. i is laminated on the outer layer o.
本発明のデラミボトルの基本的な構成によれば、胴部１０上に口頸部１１を起立した形態をなし、少なくとも胴部１０に外気導入孔ｈが形成された保形性を有する外層ｏと、外層ｏの内面に剥離可能に積層形成された可撓性の内層ｉとを備えたデラミボトルであるから、その製造の際には、内層ｉを一旦剥離収縮させた状態で外気導入孔ｈを形成し、この外気導入孔ｈを形成した後に内層ｉを拡張して外層ｏに積層すればよく、また使用時に外気導入孔ｈから内層ｉと外層ｏとの間に円滑に外気を導入することができ、その結果、容器の不正変形の発生を確実に防止でき、ポンプを装着した際の円滑な内容物の吐出が可能である。また、外層ｏに形成された外気導入孔ｈは確実に穿孔され、また、穿孔時に内層ｉに傷を発生する等の不都合を確実に防止できる。 According to the basic configuration of the Delami bottle of the present invention, the outer layer o having a shape-retaining property in which the mouth and neck portion 11 is erected on the trunk portion 10 and at least the outside air introduction hole h is formed in the trunk portion 10. Since the Delami bottle is provided with a flexible inner layer i formed in a peelable manner on the inner surface of the outer layer o , the outer air introduction hole h is formed in a state where the inner layer i is once peeled and contracted during the production. formed, smoothly introducing the outside air between the outside air introduction hole h of the inner layer i and the outer layer o this extension of the inner layer i after the outside air forming the introduction holes h may be laminated to the outer layer o are also in use As a result, it is possible to reliably prevent the container from being illegally deformed and to smoothly discharge the contents when the pump is mounted. Further, the outside air introduction hole h formed in the outer layer o is surely perforated, and it is possible to reliably prevent inconveniences such as generation of scratches on the inner layer i during perforation.
胴部１０の一部に間隔をあけて一対の凹部１２を併設し、各凹部１２を形成する外層ｏの隣接する対向壁１３に外気導入孔ｈを形成した場合には、当初各対向壁１３間の隙間に存在した内層ｉが、外層ｏに内層ｉが積層形成された状態と全く同じ元の状態に戻らずに各対向壁１３間に外気導入孔ｈと連通する隙間を形成し易く、その結果、内外層間への外気の導入をより円滑に行なえる利点がある。 In the case where a pair of recesses 12 are provided at a part of the body 10 with an interval, and the outside air introduction holes h are formed in the opposing walls 13 adjacent to the outer layer o forming the respective recesses 12, each of the opposing walls 13 is initially formed. The inner layer i existing in the gap between them does not return to the same original state as the inner layer i laminated on the outer layer o, and it is easy to form a gap communicating with the outside air introduction hole h between the opposing walls 13. As a result, there is an advantage that outside air can be introduced more smoothly between the inner and outer layers.
一対の対向壁１３にそれぞれ外気導入孔ｈを穿設し、各外気導入孔ｈに挿通して吊り下げ紐２０を装着した場合には、ボトルの取り扱いがより広範囲に便利になる。また、吊り下げ紐２０の装着もきわめて簡単に行なえる利点もある。 When the outside air introduction holes h are formed in the pair of opposing walls 13 and the hanging strings 20 are inserted through the respective outside air introduction holes h, handling of the bottle becomes more convenient in a wide range. In addition, there is an advantage that the hanging strap 20 can be attached very easily.
各凹部１２を被覆して胴部１０外周にラベル４０を装着した場合には、外観が良くなる利点ととともに、ラベル４０に種々の記載することができる利点があり、しかも、ラベル４０はその縁部と凹部１２とを連通する通気性を胴部１０との間に形成できるため、外気の導入に支障をきたす虞もない。 When the label 40 is attached to the outer periphery of the body portion 10 so as to cover each concave portion 12, there are advantages that the appearance can be improved, and various advantages can be described on the label 40, and the label 40 has its edge. Since the air permeability that allows the portion and the recess 12 to communicate with each other can be formed between the body portion 10 and the body portion 10, there is no possibility of hindering the introduction of outside air.
本発明のデラミボトルの外気導入孔形成方法は、胴部１０上に口頸部１１を起立するとともに胴部１０の一部に凹部１２を設けた形態をなし、保形性を有する外層ｏの内面に剥離可能に内層ｉを積層形成した外気導入孔未形成ボトルＡ１を、ブロー成形により形成し、次いで、外気導入孔未形成ボトルＡ１の内部を減圧して内層ｉを外層ｏより剥離収縮させ、しかる後内層ｉの剥離収縮状態で上記凹部１２内の外層ｏ部分に外気導入孔ｈを穿設し、次いで、剥離収縮状態の内層ｉ内をブロー加圧して内層ｉを拡張し、内層ｉを外層ｏに積層したので、上記した特徴を備えたデラミボトルの形成が可能であるとともに、外気導入孔の穿孔に当たって内層を損傷することもなく行なえる特徴がある。しかも、その操作工程も煩雑でなく、外気導入孔の容易な穿孔が可能である。
The method for forming an outside air introduction hole for a delami bottle of the present invention has a form in which a mouth and neck part 11 is erected on the body part 10 and a recess 12 is provided in a part of the body part 10, and the inner surface of the outer layer o having shape retention The outside air introduction hole non-formed bottle A1 in which the inner layer i is formed in a peelable manner is formed by blow molding, and then the inside of the outside air introduction hole non-formed bottle A1 is depressurized to cause the inner layer i to peel and shrink from the outer layer o. Thereafter, an outside air introduction hole h is formed in the outer layer o in the recess 12 in the peeled and contracted state of the inner layer i, and then the inner layer i is expanded by blowing and pressurizing the inner layer i in the peeled and contracted state. Since it is laminated on the outer layer o, it is possible to form a Delami bottle having the above-described characteristics, and it is possible to perform without damaging the inner layer when perforating the outside air introduction hole. In addition, the operation process is not complicated, and the outside air introduction hole can be easily drilled.
以下、本発明の形態を図面を参照して説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
図１乃至図３は本願発明デラミボトルＡの第１実施例を示し、デラミボトルＡは、胴部１０上に口頸部１１を起立した形態をなし、また、少なくとも胴部１０に外気導入孔ｈが形成された保形性を有する外層ｏと、可撓性の内層ｉとから構成されている。尚、胴部１０は、周壁部１０ａの上端より肩部１０ｂを延設して構成しており、周壁部１０ａの下端開口を底部１４で閉塞している。また、便宜上、図１に於けるデラミボトルＡを、向かって左方を前部、向かって右方を後部、手前を右部、奥方を左部として説明する。 FIG. 1 to FIG. 3 show a first embodiment of the Delami bottle A of the present invention. The Delami bottle A has a form in which the mouth and neck portion 11 is erected on the trunk portion 10, and at least the outside portion 10 has an outside air introduction hole h. The outer layer o having shape retention and the flexible inner layer i are formed. In addition, the trunk | drum 10 is comprised by extending the shoulder part 10b from the upper end of the surrounding wall part 10a, and has closed the lower end opening of the surrounding wall part 10a with the bottom part 14. FIG. For the sake of convenience, the delami bottle A in FIG. 1 will be described with the left side toward the front, the right side toward the rear, the near side toward the right, and the back toward the left.
外気導入孔ｈは胴部１０の外層ｏに設けられたもので、収容物の減少に伴って剥離収縮する内層ｉと外層ｏとの間に、ここから外気を導入するためのものであり、少なくとも胴部１０を構成する外層ｏに設け、さらに口頸部１１を構成する外層ｏに設けても良い。本例では，胴部１０の後部上部に間隔をあけて一対の凹部１２を併設し、各凹部１２を形成する外層ｏの隣接する対向壁１３にそれぞれ外気導入孔ｈを形成している。各凹部１２は、それぞれ外側面及び外面を開口して形成されており、換言すれば、後部より向かって左側の凹部１２では、後部より向かって左側面及び後面が、後部より向かって右側の凹部１２では、後部より向かって右側面及び後面がそれぞれ開口した凹部形態をなしている。そして、それぞれ凹部１２を形成し、互いに対向する内側の対向壁１３に、それぞれ外気導入孔ｈを穿設している。また、この外気導入孔ｈには、二点鎖線で示す如き吊り下げ紐２０を挿通装着することができる。 The outside air introduction hole h is provided in the outside layer o of the body portion 10, and is for introducing outside air between the inside layer i and the outside layer o, which peels and contracts as the contents are reduced, It may be provided in at least the outer layer o constituting the trunk portion 10 and further provided in the outer layer o constituting the mouth neck portion 11. In this example, a pair of recesses 12 are provided in the rear upper part of the body 10 with a space therebetween, and the outside air introduction holes h are formed in the opposing walls 13 adjacent to the outer layer o forming each recess 12. Each recess 12 is formed by opening the outer surface and the outer surface, in other words, in the recess 12 on the left side from the rear, the left side and the rear surface from the rear are recessed on the right side from the rear. No. 12 has a concave shape in which the right side surface and the rear surface are opened from the rear. And the recessed part 12 is formed, respectively, and the external air introduction hole h is pierced in the inner opposing wall 13 which mutually opposes. In addition, a hanging string 20 as shown by a two-dot chain line can be inserted into the outside air introduction hole h.
また、デラミボトルＡは、外層ｏの内面に剥離可能に積層形成された内層ｉを一旦剥離収縮させた状態で外気導入孔ｈが形成され、外気導入孔ｈ形成後に内層ｉを拡張して外層ｏに積層させて形成される。この場合の内層ｉの剥離状態は、外層ｏに対して内層ｉ全体の剥離を対象としているが、実質的には、例えば、口頸部１１の上部、底部１４の一部等に非剥離部分がある。この様な剥離状態は、容器内の減圧で現出可能である。尚、内層ｉと外層ｏとの間に、口頸部１１から胴部１０を介して底部１４至る部分にかけて剥離不能な少なくとも１本の接着層を設けることも可能である。 Further, the delami bottle A is formed with an outside air introduction hole h in a state in which the inner layer i formed in a peelable manner on the inner surface of the outer layer o is once peeled and contracted, and after the outside air introduction hole h is formed, the inner layer i is expanded to expand the outer layer o. It is formed by laminating. The peeled state of the inner layer i in this case is intended for peeling of the entire inner layer i with respect to the outer layer o. However, in practice, for example, the upper part of the mouth / neck part 11, a part of the bottom part 14, etc. There is. Such a peeled state can be manifested by the reduced pressure in the container. It is also possible to provide at least one adhesive layer that cannot be peeled between the inner layer i and the outer layer o from the neck portion 11 to the bottom portion 14 via the trunk portion 10.
この様な外気導入孔ｈを形成する方法として、本願発明の外気導入孔ｈの形成方法を以下に説明する。まず、図４（ａ）に示す如く、まず、胴部１０上に口頸部１１を起立した形態をなし、保形性を有する外層ｏの内面に剥離可能に内層ｉを積層形成した外気導入孔未形成ボトルＡ１をブロー成形により形成する。外気導入孔未形成ボトルＡ１は、前述した図２に示す如き一対の凹部１２が形成されており、この状態で外気導入孔ｈは形成されていない。ブロー成形としては、例えば、射出成形により形成された有底パリソンを所定の型内に吹き込み拡張して型通りの形成体を得るインジェクションブロー成形を採用でき、その他一般的なブロー成形方法が採用される。 As a method for forming such an outside air introduction hole h, a method for forming the outside air introduction hole h of the present invention will be described below. First, as shown in FIG. 4A, first, an outside air introduction in which a mouth-and-neck portion 11 is erected on the trunk portion 10 and an inner layer i is laminated on the inner surface of the outer layer o having shape retention so as to be peeled off. The hole-unformed bottle A1 is formed by blow molding. The outside air introduction hole non-formed bottle A1 has a pair of recesses 12 as shown in FIG. 2 described above, and the outside air introduction hole h is not formed in this state. As blow molding, for example, injection blow molding can be adopted in which a bottomed parison formed by injection molding is blown into a predetermined mold to obtain a molded product as it is, and other general blow molding methods are employed. The
次いで、外気導入孔未形成ボトルＡ１の内部を減圧して、図４（ｂ）に示す如く、内層ｉを外層ｏより剥離収縮させる。減圧には口頸部１１内へ減圧ノズル３０を挿入して内部を減圧することで、内層ｉのほとんど全体を外層ｏから剥離し、収縮させ、内層剥離状態の外気導入孔未形成ボトルＡ２を形成する。本例では内層ｉの口頸部１１を構成する部分の上部及び底部１４を構成する内層ｉの中央部一部は連結状態にある。 Next, the inside of the outside air introduction hole non-formed bottle A1 is decompressed, and the inner layer i is peeled and contracted from the outer layer o as shown in FIG. For decompression, the decompression nozzle 30 is inserted into the mouth and neck portion 11 to decompress the inside, so that almost the entire inner layer i is peeled from the outer layer o and contracted, and the outside air introduction hole unformed bottle A2 in the inner layer peeled state is obtained. Form. In this example, the upper part of the portion constituting the mouth / neck portion 11 of the inner layer i and the central portion of the inner layer i constituting the bottom portion 14 are in a connected state.
次いで、図４（ｃ）に示す如く、内層ｉの剥離収縮状態で外層ｏに外気導入孔ｈを穿設する。この場合には、各凹部１２の隣接する対向壁１３にそれぞれ外気導入孔ｈを穿設し、内層剥離状態のデラミボトルＡ３を形成する。外気導入孔ｈの穿設方法としては、合成樹脂の穿孔に通常使用されている穿孔器具、例えばパンチカッター等での穿孔が可能であるが特に限定することはない。 Next, as shown in FIG. 4C, an outside air introduction hole h is formed in the outer layer o in a state of peeling contraction of the inner layer i. In this case, an outside air introduction hole h is formed in each of the opposing walls 13 adjacent to the respective recesses 12 to form a delamination bottle A3 in an inner layer peeled state. A method for drilling the outside air introduction hole h is not particularly limited, although it is possible to perform drilling with a drilling tool that is usually used for drilling synthetic resin, such as a punch cutter.
尚、外気導入孔ｈは、この様な凹部１２の対向壁１３に穿設する場合に限らず、胴部１０を構成する外層ｏに直接穿孔しても良い。例えば、胴部１０の周壁部１０ａ、胴部１０の肩部１０ｂに直接穿孔しても良い。また、必要に応じて、口頸部１１に外気導入孔ｈを穿設しても良く、胴部１０、口頸部１１に複数の外気導入孔ｈを穿設することも可能である。また、凹部１２を形成する場合、上記した一対の凹部１２を設ける場合に限らず、一箇所の凹部を設け、その凹部を形成する周壁部分に外気導入孔ｈを穿設しても良い。必要あらば当然三箇所以上の凹部を設けてその凹部を形成する周壁部分に外気導入孔ｈ穿設することも可能である。また、外層ｏのみにカッター等で切断開口して外気導入孔ｈを形成することも可能であり、外気導入孔ｈの形状としては図示例の如き円形に限らずスリット状であっても良く、その他の形状であっても良く特に限定されない。 In addition, the outside air introduction hole h is not limited to the case of being formed in the facing wall 13 of the concave portion 12, and may be directly formed in the outer layer o constituting the body portion 10. For example, the peripheral wall portion 10 a of the trunk portion 10 and the shoulder portion 10 b of the trunk portion 10 may be directly drilled. Further, if necessary, the outside air introduction hole h may be formed in the mouth / neck portion 11, and a plurality of outside air introduction holes h may be formed in the body portion 10 and the mouth neck portion 11. Moreover, when forming the recessed part 12, you may provide not only the case where the above-mentioned pair of recessed part 12 is provided, but provide the recessed part of one place, and you may drill the external air introduction hole h in the surrounding wall part which forms the recessed part. If necessary, it is of course possible to provide three or more concave portions and to form the outside air introduction hole h in the peripheral wall portion forming the concave portions. Further, it is possible to form the outside air introduction hole h by cutting and opening only the outer layer o with a cutter or the like, and the shape of the outside air introduction hole h is not limited to a circle as in the illustrated example, and may be a slit shape, Other shapes may be used and are not particularly limited.
次いで、図４（ｄ）に示す如く、剥離収縮状態の内層ｉ内をブロー加圧して内層ｉを拡張し、内層ｉを外層ｏに積層する。加圧には、例えば、口頸部１１内へ加圧ノズル３１を挿入して内部をブロー加圧させ、外層ｏに内層ｉが積層したデラミボトルＡが形成される。尚、この際、各凹部１２の各対向壁１３間の離間幅等が狭い場合には一旦剥離した内層ｉは各対向壁１３間の隙間に戻らずに、各対向壁１３間に空間のある状態で内層ｉが外層ｏに積層されるため、より外気の導入が円滑化される。 Next, as shown in FIG. 4D, the inner layer i in the peeled and contracted state is blown and pressurized to expand the inner layer i, and the inner layer i is laminated on the outer layer o. For the pressurization, for example, a pressurizing nozzle 31 is inserted into the mouth-and-neck portion 11 to blow-pressurize the inside, and the delamination bottle A in which the inner layer i is laminated on the outer layer o is formed. At this time, if the separation width between the opposing walls 13 of each recess 12 is narrow, the inner layer i once peeled does not return to the gap between the opposing walls 13, and there is a space between the opposing walls 13. Since the inner layer i is laminated on the outer layer o in the state, the introduction of the outside air is further facilitated.
上記の如く構成されたデラミボトルＡは、例えば、内部に収容物を収納した後、口頸部１１に吐出用のポンプを装着して使用される。ポンプの作用で収容液が吐出されると、内部の負圧化で内層ｉが収縮し、外気導入孔ｈから内層ｉと外層ｏとの間に外気が導入される。 The delami bottle A configured as described above is used by, for example, storing a container therein and then mounting a discharge pump on the mouth and neck portion 11. When the stored liquid is discharged by the action of the pump, the inner layer i contracts due to the negative pressure inside, and the outside air is introduced between the inner layer i and the outer layer o through the outside air introduction hole h.
図５は第２実施例を示し、第１実施例の外気導入孔ｈに加えて、さらに口頸部１１を構成する外層ｏに外気導入孔ｈを穿設した例を示す。本例の場合も、図１の例の場合と同様の外気導入孔ｈの形成が可能であり、特に説明を省略する。 FIG. 5 shows a second embodiment, in which an outside air introduction hole h is formed in the outer layer o constituting the mouth neck portion 11 in addition to the outside air introduction hole h of the first embodiment. Also in the case of this example, it is possible to form the outside air introduction hole h similar to the case of the example of FIG.
図６は第３実施例を示し、図１の例に於いて、ラベル４０を装着した例を示す。本例ではラベル４０としてシュリンクラベルを、各凹部１２を被覆して胴部１０外周に装着している。 FIG. 6 shows a third embodiment, and shows an example in which a label 40 is attached in the example of FIG.
